What percent is represented by the shaded area khan academy

Answer:

The answered would be 1/64 since it's simplified

Answer:

I think the exact form is 1/64

Answer:

$2,184

Step-by-step explanation:

$6,500 x 2.8% = annual interest

6,500 x 2.8% = $182 annual interest

$182 x 12 years = interest earned in 12 years.

182 x 12 = $2,184

[tex]\huge\boxed{\left \{ {{x+y=3} \atop {3x-y=5}} \right.}[/tex]

We can solve this problem by testing the solution against each system of equations. We'll do this by substituting the point into each equation for each system.

[tex]\begin{array}{c|c}\textbf{First Equation}&\textbf{Second Equation}\\\cline{1-2}\begin{aligned}2x+y&=5\\2(2)+1&=5\\4+1&=5\\5&=5\\&\checkmark\end{aligned}&\begin{aligned}-2x+y&=2\\-2(2)+1&=2\\-4+1&=2\\-3&=2\\&\text{X}\end{aligned}\end{array}[/tex]

[tex]\begin{array}{c|c}\textbf{First Equation}&\textbf{Second Equation}\\\cline{1-2}\begin{aligned}-2x-y&=-5\\-2(2)-1&=-5\\-4-1&=-5\\-5&=-5\\&\checkmark\end{aligned}&\begin{aligned}2x-y&=2\\2(2)-1&=2\\4-1&=2\\3&=2\\&\text{X}\end{aligned}\end{array}[/tex]

[tex]\begin{array}{c|c}\textbf{First Equation}&\textbf{Second Equation}\\\cline{1-2}\begin{aligned}-x+y&=3\\-2+1&=3\\-1&=3\\&\text{X}\end{aligned}&\begin{aligned}-3x+y&=-5\\-3(2)+1&=-5\\-6+1&=-5\\-5&=-5\\&\checkmark\end{aligned}\end{array}[/tex]

[tex]\begin{array}{c|c}\textbf{First Equation}&\textbf{Second Equation}\\\cline{1-2}\begin{aligned}x+y&=3\\2+1&=3\\3&=3\\&\checkmark\end{aligned}&\begin{aligned}3x-y&=5\\3(2)-1&=5\\6-1&=5\\5&=5\\&\checkmark\end{aligned}\end{array}[/tex]

Since both equations in the final system are true when solved with [tex](2, 1)[/tex], the answer is the last system.

Answer:

division property of equality

Step-by-step explanation:

The property used in the last step to find x = 10 in the expression is the division property of equality.

      8(x-2) = 64

      8x-18 = 84

        8x = 80

         x = 10

In 8x = 80 ;

 Division property of equality was used to find the value of x.

The property states that when we divide both sides by a non-zero value, the two sides remains the same.

Answer:

It is not proportional because it does not pass through the origin (0,0)

Answer:

29. 9p(2p+1)(2p-1)

31. 4k(2k+5)(2k-5)

Step-by-step explanation:

29. 9p(36p^3/9p-9p/9p)

9p(4p^2-1)

9p((2p)^2-1^2)

9p(2p+1)(2p-1)

31. 4k(16k^3/4k+-100k/4k)

4k(4k^2-25)

4k((2k)^2-5^2)

4k(2k+5)(2k-5)

Answer:

Step-by-step explanation:

To evaluate f(7) substitute x = 7 into f(x), that is

f(7) = 268 - 22(7) = 268 - 154 = 114

Answer:

Values if y:

-3

2

7

12

17

22

Answer:

if y= 5x+7 answer is

-3, 4, 7, 10, 22

Step-by-step explanation:

out put = input 5x+7

the u get these answers:

-3, 4, 7, 10, 22

Answer:

y= -6/5x -3

Step-by-step explanation:

So for now lets bring it into mx + b format

Subtract 6x from both sides to isolate y which is also called subtraction property of equality.

so 5y = -6x -15

Now you divide both sides by 5 which is called division property of equality.

You now have y = -6/5x - 3

y= -6/5x -3 is the slope intercept form of the standard form equation of 6x + 5y = -15.

Hope this helps!

Answer:

C. Write the first equation in standard form.

Answer:

no

Step-by-step explanation:

Given:

Total number of invited people = 450

Total number of people who accept the invitation = 315

To find:

The percent of the people who accepted the invitation.

Solution:

We need to find 315 is what percent of 450.

[tex]\%=\dfrac{\text{Number of invited people - Who accept the invitation}}{\text{Number of invited people}}\times 100[/tex]

[tex]\%=\dfrac{450-315}{450}\times 100[/tex]

[tex]\%=\dfrac{135}{45}\times 10[/tex]

[tex]\%=3\times 10[/tex]

[tex]\%=30[/tex]

Therefore, 30% of the people accepted the invitation.

Answer:

b + 13y

Step-by-step explanation:

4b + 5y - 3b + 8y = 4b - 3b + 5y + 8y

I rearranged the like terms together.

4b - 3b + 5y + 8y = b + 13y

Simplify.

Answer:

The angle for C is 28°.

Step-by-step explanation:

In a cyclic quadrilateral, opposite angles are supplementary which means that both angles add up will be 180° :

∠A + ∠C = 180°

152° + ∠C = 180°

∠C = 180° - 152°

∠C = 28°
